Description

  The present invention relates to a method for forming a wall of an outer frame provided along a site boundary part or an adjacent land boundary part of a house or an apartment.

  In general, as a panel for an external frame provided along the boundary of a site such as a house or factory, a rectangular panel made of metal, wood, concrete, synthetic resin, etc. It is proposed to have a material attached. This crosspiece is used for joining with a support column, for attaching with a headboard, a cover material for makeup, etc. from the viewpoint of purpose, workability, and design. Various things have been proposed.

  For example, in a dry-type dredge in which a column member is erected at a predetermined interval, a horizontal beam member is installed between the opposite column members, and a side panel is fixed to the horizontal column member, the outer side surface of the opposing protrusions There has been proposed a dry type scissor characterized in that both ends of the crosspiece are fixed to each other and the support member and the outer surface of the side panel are arranged on the same surface.

  Since this dry bag has the support member and the outer surface of the side panel arranged on the same surface, there is a sense of unity between the panel material and the support member, and an excellent design can be achieved (for example, Patent Documents) 1).

  In addition, a partition wall is proposed in which a hollow portion is formed between a pair of wall plates, and the hollow portion is filled with gypsum board, glass wool, or the like. This can improve the sound insulation, heat insulation and strength of the partition wall (see, for example, Patent Document 2).

JP-A-9-19592 JP 2000-73474 A

  However, the dry soot described in Patent Document 1 has the following problems. That is, in general, the column member is first erected, and the side panel is fixed with a predetermined curing period, so that the construction period is relatively long, and the column member is first erected. The problem was that it was difficult to absorb the construction errors that occurred. Further, the partition wall described in Patent Document 2 has the following problems. That is, since the sound absorbing performance and heat insulation are mainly improved, the sound absorbing property is not taken into consideration, and the point is insufficient.

  The present invention eliminates the above-described problems and provides a sound insulation rod having a sound insulation performance and a sound insulation performance and a sound absorption performance in a method for forming a collar in which a column can be attached to the back side of the frame of the collar. At the same time, the present invention is to provide a method for forming a soot that can be selected from a sound absorbing soot that is designed to supplement the sound insulation performance.

In order to achieve the above object, the present invention is configured as follows. That is, the scissors according to the present invention are attached to the inside of a frame made up of two vertical members and two cross members facing each other, with a front plate and a non-opening back plate spaced at the front and rear, On the opposing surfaces of the longitudinal member and the transverse member, groove portions into which the end portions of the front plate and the rear plate are inserted in the longitudinal direction are provided at intervals in the front and rear, and the groove portions provided in the longitudinal member are The outer wall located on the front side of the front plate or the back plate, and the inner side wall located on the back side of the front plate or the back plate, provided integrally with the longitudinal member, The space between the outer wall and the outer side wall is wider than the base side, and the protrusion is projected toward the back side of the front plate and the back plate inserted from the front end of the outer wall. .
Further, according to the method of forming a ridge according to the present invention, a front plate and a non-opening back plate are spaced apart in the front and rear sides inside a frame made up of two vertical members and two cross members facing each other. Groove portions into which the end portions of the front plate and the back plate are inserted in the longitudinal direction are provided on the opposing surfaces of the longitudinal member and the transverse member at an interval in the front-rear direction. The groove portion formed integrally with the longitudinal member is composed of an outer wall located on the front surface side of the front plate or the back plate and an inner wall located on the rear surface side of the front plate or the back plate. 2. The scissors according to claim 1, wherein the front end portion has a wider distance from the outer wall than the base side, and the protrusion protrudes from the front end of the outer wall toward the back side of the front plate and the rear plate. When forming the non-opening plate and the opening plate as the front plate, the non-opening plate is used as the front plate. In the case of forming a sound insulation wall, an opening plate is attached as a front plate, and noise that has entered into the hollow portion from the opening of the opening plate is absorbed by a sound absorbing material, thereby providing sound absorption and opening plate on the front plate. It was made to compensate for the deterioration of the sound insulation performance due to the use of a metal plate placed on the front surface of the back plate, and to form a sound absorbing kite, and to select either one to form a kite It is what.

  According to the method for forming a crease according to the present invention, a sound insulation crease is formed by attaching a non-opening plate as a front plate, and an opening plate is attached as a front plate, and noise that has entered the hollow portion from the opening of the opening plate is absorbed. By absorbing sound with a material, it has sound absorption and forms a sound absorbing bowl by compensating for the decrease in sound insulation performance due to the use of a non-opening plate on the front plate with a metal plate placed on the front of the back plate If you only need to block the noise generated from the noise source according to the installation location, select the sound insulating fence and select the noise source. If you want to block out the noise generated by the heel and absorb the noise itself with the heel, you can select the sound-absorbing heel. Open plate or front plate The front surface of the back plate with the aperture plate made possible by relatively simple recombination operation such or placing a metal plate.

  Further, in the crease formation method according to the crease formation method according to the present invention, if the width dimension before and after the hollow portion is set to 35 to 60 mm, the sound insulation performance and the sound absorption performance are maintained and compared as described later. Light weight and relatively easy to carry.

  Next, the best mode for carrying out the present invention will be specifically described with reference to the drawings.

  That is, FIG. 1 is a front view showing an embodiment of a sound insulation fence made by the method for forming a fence according to the present invention, FIG. 2 is an enlarged cross-sectional view of the main part in the AA section of FIG. 1, and FIG. FIG. 4 is a plan view showing an embodiment of the front plate and the back plate, and FIG. 5 is an implementation of the sound absorbing bag produced by the method for forming the bag according to the present invention. FIG. 6 is an exploded explanatory view showing an embodiment of a mounting structure between a heel and a column in a ridge created by the ridge formation method according to the present invention.

  In the drawings, reference numeral 1 denotes a frame body comprising two vertical members 11 and two cross members 12 facing each other, and 2 and 3 a front plate 2 attached to the inside of the frame body 1 with an interval in the front-rear direction; The non-opening back plates 3 and 4 are sound-absorbing materials housed in a hollow portion 5 formed between the front plate 2 and the back plate 3, and the soot formed by the soot forming method according to this embodiment is The frame 1, the front plate 2, the back plate 3, and the sound absorbing material 4 are mainly configured.

  The front plate 2 is formed in a substantially rectangular shape as shown in FIG. 1, and a metal plate 22 is bonded to the front and back surfaces of the core material 21 as shown in FIG. The core material 21 is generally made from a thermoplastic synthetic resin such as polyethylene or polypropylene, and may be made of polyethylene, polypropylene alone, or a kneaded mixture of these, and hydroxylated to them. What knead | mixed inorganic materials, such as aluminum and magnesium hydroxide suitably, may be used. The metal plate 22 is generally made of aluminum, but may be made of other metals such as stainless steel and copper. The metal plate 22 arranged on the outside is coated to enhance the decorativeness. Or, a decorative sheet or film may be attached, but it may be used as it is.

  As shown in FIG. 4B, the back plate 3 has the same configuration as that of the front plate 2, that is, a metal plate 32 attached to the front and back surfaces of the core material 31.

In the present embodiment, the front plate 2 and the back plate 3 are laminated bodies composed of the core materials 21 and 31 and the metal plates 22 and 32. However, the front plate 2 and the rear plate 3 are not limited to the laminated body. Alternatively, the core material 21 may be used alone, or may be formed of a translucent material made of polycarbonate, acrylic resin, or the like, in accordance with the performance required for the sound insulation, sound absorption, translucency, etc. It can be selected appropriately.

In this embodiment, the sound absorbing material 4 is a cotton-like assembly composed of thermoplastic synthetic resin fibers, and is formed into a sheet shape, the size of which is the same as that of the front plate 2 and the back plate 3 , As shown in FIG. 2, FIG. 3 and FIG. 5, it is housed in a hollow portion 5 formed between the front plate 2 and the back plate 3. The thickness of the sound absorbing material 4 may be approximately the same as the width dimension before and after the hollow part 5, but it may be set to be thicker than the width dimension so as to be pushed into the hollow part 5.

In this embodiment, the material of the sound absorbing material 4 is polyester having polyethylene terephthalate as a main component, but it may be appropriately kneaded or copolymerized with polyester such as polybutylene terephthalate or polyethylene isophthalate. Further, synthetic resins such as polyethylene, polypropylene, acrylic resin, and polyamide may be used. Furthermore, when producing a fiber with these synthetic resins, you may comprise a fiber so that it may consist of a core part and the coating | coated part arrange | positioned on the outer periphery. In short, when the sound-absorbing material 4 is installed in the hollow portion 5, an external force is applied from the outside of either the front plate 2 or the back plate 3 due to wind, vibration, noise, etc., and either the front plate 2 or the back plate 3 is applied. When one side is bent toward the sound absorbing material 4, the bending is elastically absorbed by the sound absorbing material 4 so that the bending does not propagate to the other front plate 2 and the back plate 3 , and the external force is lost. Any material can be used as long as the sound absorbing material 4 can be configured to return to the original state.

  The form of the sound-absorbing material 4 is a synthetic resin fiber having a length of 30 to 100 mm and a thickness of 5 to 100 μm in this embodiment, but is not particularly limited to this. In order to produce an end length panel, it is preferable that when the sound absorbing material 4 is cut at a construction site or the like, even if the cut ends are scattered, they are unlikely to pierce the operator's skin and cause unpleasant stimulation. .

  As shown in FIG. 2, the vertical member 11 is attached opposite to the side end portions of the two front plates 2 and the rear plate 3 that are arranged at intervals in the front-rear direction. In the substrate 111, groove portions 112 into which the side end portions of the panel body 1 are respectively inserted are erected in the longitudinal direction. In this embodiment, the groove 112 is erected from both ends of the substrate 111, but can be formed at any position on the substrate 111.

The groove portion 112 of the vertical member 11 includes an outer wall 113 positioned outside the front plate 2 and the back plate 3 and an inner wall 114 positioned inside the front plate 2 and the back plate 3. The distance between the outer side wall 113 and the inner side wall 114 is slightly larger than the thickness of the front plate 2 and the rear plate 3 , and the end of the inner side wall 114 is widened with the outer wall 113. Furthermore, the front end corner of the inner side of the inner wall 114 is cut away to form a slope. Thereby, it becomes easy to insert the front plate 2 and the back plate 3 into the groove portion 112.

Further, when the side edge of the front plate 2 or the back plate 3 is inserted into the groove portion 112, the inner edge of the front plate 2 or the back plate 3 is brought into contact with the back of the inner side wall 114, and the front plate 2 or The outer end portion of the back plate 3 abuts on the front end of the projection 115 protruding from the end portion of the outer wall 113 of the groove portion 112 toward the front plate 2 or the back plate 3. Thereby, the side edge parts of the front plate 2 and the back plate 3 can be fixed in the groove 112.

  Further, if both end portions of the front plate 2 or the back plate 3 are respectively inserted into the grooves 112 of the longitudinal members 11 facing each other, the front plate 2 or the back plate 3 is bent from the inside to the outside. When an external force is applied, the protrusion 115 and the inner wall 114 of the outer wall 113 of the groove 112 that is in contact with the side edge of the front plate 2 or the back plate 3 act so as to prevent the occurrence of bending. , It is difficult for the bending to occur.

  As shown in FIG. 3, the cross member 12 is attached to the upper and lower ends of the front plate 2 and the back plate 3 so as to face each other. And like the vertical member 11, the groove part 122 is standingly arranged toward the inner side where the front plate 2 or the back plate 3 is attached. The structure of the groove 122 is the same as that of the groove 112 of the longitudinal member 11.

  The vertical member 11 and the horizontal member 12 are generally made of a member obtained by cutting a long mold material obtained by extrusion molding of aluminum into an appropriate length, and are relatively light when forming and transporting a ridge. It is easy to carry, but it is a metal other than aluminum, or a composite material of metal or inorganic material and synthetic resin, for example, a synthetic resin laminated with a metal film, a colored surface, or a surface to improve decoration Depending on the required strength, such as those having irregularities formed on the surface can be used as appropriate.

  The saddle shown in FIG. 2 has a configuration of a sound insulation fence for suppressing noise generated on the front plate 2 side from propagating to the back plate 3 side and effectively insulating the sound, as shown in FIG. The generated soot relates to a sound absorbing soot that is configured to effectively absorb the generated noise.

That is, it is the same as the sound absorbing box shown in FIG. 2 in that the sound absorbing material 4 is housed in a hollow portion formed between the front plate 2 and the back plate 3 provided with a space in the front and rear direction. The front plate 2 is provided with a large number of through holes 23 on the entire surface thereof, and the metal plate 6 is disposed on the front surface of the back plate 3. As a result, the noise is obtained by absorbing the noise that has entered the hollow portion 5 from the through hole 23 of the front plate 2 with the sound absorbing material 4, thereby providing sound absorption and using the aperture plate for the front plate 2. The decrease in sound absorption performance is compensated by a metal plate disposed on the front surface of the back plate 3. The metal plate 6 is a steel plate in this embodiment, but may be another metal or may be plated with zinc or the like in order to improve corrosion resistance. If the metal plate 6 is disposed on the front surface of the back plate 3, the effect is obtained, so that the peripheral end portion of the metal plate 6 is the groove portion 112 of the vertical member 11 and the groove portion 122 of the cross member 12 in the same manner as the back plate 3. It may be inserted into the front plate or may be simply disposed on the front surface of the back plate 3. In the latter case, the upper and lower ends of the metal plate 6 are folded to the sound absorbing material 4 side, respectively, and the folded portions are arranged so as to be positioned at the upper and lower ends of the sound absorbing material 4, so that the metal plate 6 is not prepared. It may be made not to move to. When the noise source is on the back side, the back plate 3 may be an aperture plate and the front plate may be a non-open plate.

  Subsequently, a connection structure between the ridge formed by the ridge formation method according to this embodiment and the support column 7 will be described. As shown in FIGS. 3 and 5, the cross member 12 is provided with a column mounting groove 123 along the longitudinal direction on the side in contact with the column 7, and the column mounting member 8 is slidably inserted into the column mounting groove 123. It is what is done. The column mounting groove 123 is provided with an opening 124 along the longitudinal direction on the side in contact with the column 7, and the opening 124 is shorter than the vertical dimensions of the column mounting groove 123 and the column mounting member 8. The longitudinal member 11 is provided with an insertion hole for inserting the column attachment member 8 into the column attachment groove 123.

  FIG. 6A is an exploded perspective view showing an outline of the connection structure, and FIG. 6B is an enlarged view of a main part thereof. The mounting bolt 9 is inserted into the through hole 71 provided in the support column 7 and the support column 7 is penetrated. Next, the threaded portion of the mounting bolt 9 is passed through the opening 124 and screwed into the mounting hole 81 of the column mounting member 8 inserted into the column mounting groove 123. Thereby, the cross member 12 is fixed to the column 7.

  Moreover, when connecting the eaves produced by the eaves forming method according to the present invention, an embodiment in which an elastic member such as packing is disposed at the connection portion is preferable. As a result, it is possible to fill in gaps caused by construction errors such as machining errors and inclinations in the two ridges adjacent to the left and right, reducing noise propagated from these gaps, and improving sound absorption performance and sound insulation performance. Can do. A similar packing may be disposed between the cage and the ground.

  Next, as for the width dimension in the front-rear direction of the hollow part c, it was confirmed how much the thickness can be increased to increase the sound absorption coefficient. That is, creases composed of A to C formed by the crease formation method according to the present invention were prepared, and the relationship between the width dimension and the sound absorption coefficient was measured for each, and the results are shown in Table 2. In addition, the judgment of performance is described on page 6 in the design guideline No. 5 traffic management facilities (sound insulation wall design guideline) by the three companies of East Japan Road Co., Ltd., Naka Nippon Road Co., Ltd., and West Japan Road Co., Ltd. It was measured based on a test method of “sound absorption rate”.

塀 A. The width dimension of the front and rear of the hollow portion c formed between the front plate a and the rear plate b is set to 20 mm, the sound absorbing material d is provided in the hollow portion c, and a 0.8 mm steel plate is provided in front of the rear plate b. The one arranged.
塀 B. The width dimension of the front and rear of the hollow portion c formed between the front plate a and the rear plate b is set to 30 mm, the sound absorbing material d is provided in the hollow portion c, and a 0.8 mm steel plate is provided in front of the rear plate b. The one arranged.
塀 C. The width dimension of the front and rear of the hollow portion c formed between the front plate a and the rear plate b is set to 40 mm, the sound absorbing material d is provided in the hollow portion c, and a 0.8 mm steel plate is further provided in front of the rear plate b. The one arranged.

  The front plate a and the back plate b were composite plates having a thickness of 3 mm in which a metal plate made of aluminum was attached to the front and back surfaces of a core material made mainly of polyethylene. Furthermore, the aperture ratio of the front plate a was about 25%.

  From the above measurement results, as the width dimension in the front-rear direction of the hollow part c is increased, the sound absorption rate is improved particularly on the low wavenumber side. From the results, the width dimension in the front-rear direction of the hollow part c is more than 35 mm. It was found that if it is thick, it exceeds the above-mentioned standard and the sound absorption rate can be improved suitably, and if the width dimension is 40 mm, the sound absorption rate can be improved more suitably. Further, it has been found that if the aperture ratio of the front plate a is in the range of 15 to 50%, the sound absorbing performance is not significantly affected.

  Subsequently, with respect to the width dimension in the front-rear direction of the hollow portion c, it was confirmed how much the width dimension can be increased to increase the transmission loss. That is, the heels made of D to E formed by the heel forming method according to the present invention were prepared, and the relationship between the width dimension and the sound insulation rate was measured for each, and the results are shown in Table 2. In addition, the judgment of performance is described on page 6 in the design guideline No. 5 traffic management facilities (sound insulation wall design guideline) by the three companies of East Japan Road Co., Ltd., Naka Nippon Road Co., Ltd., and West Japan Road Co., Ltd. It was measured based on the “transmission loss” test method.

塀 D. The width dimension before and behind the hollow part c formed between the front plate a and the back plate b is 40 mm, and the sound absorbing material d is internally provided in the hollow part c.
塀 E. The width dimension of the front and rear of the hollow part c formed between the front plate a and the rear plate b with an aperture ratio of 25% is set to 40 mm, the sound absorbing material d is provided in the hollow part c, and the back plate b A 0.8mm steel plate is placed on the front surface of the steel plate (same specifications as 塀 C).

  The front plate a and the back plate b were composite plates having a thickness of 3 mm in which a metal plate made of aluminum was attached to the front and back surfaces of a core material made mainly of polyethylene.

  From the above measurement results, it exceeds the reference value in the specifications of 塀 D to E, and from a number of results, if the thickness of the sound absorbing material is greater than 35 mm, it exceeds the reference and can suitably improve the sound insulation rate. It was also found that if the width dimension is 40 mm, the sound absorption rate can be improved more suitably. In addition, when comparing 塀 D and 塀 E, the front plate a is a non-opening plate, and the 塀 D that does not use a steel plate has a remarkably high transmission loss on the relatively high frequency side. It was found that 塀 E using a steel plate has a high transmission loss on the relatively low wavenumber side, and can be appropriately selected according to the frequency of the noise to be sound-insulated.

  On the other hand, regarding the upper limit of the width dimension in the front-rear direction of the hollow portion c, generally, the thicker the thickness, the higher the sound absorbing property and the sound insulating property, but the thinner one is more preferable in consideration of the workability when transporting and attaching the bag. Thereby, when the width dimension in the front-rear direction of the hollow portion c is set to 35 to 60 mm, it is possible to improve the workability when transporting and attaching the bag while exhibiting excellent sound insulation and sound absorption. It was found to be 40-60 mm.
